Title: Etching polymer coating off e.g. terminals - and detecting radiation intensity from face which is etched to determine if enough coating has gone
Inventor: HAMANN CHRISTOPH DIPL ING
IPC: B23K26/362
Filed: 1989-04-26
Abstract: In a process of thermal etching by laser beams one material is removed from another material. The degree of etching is checked by the presence of the first and/or the second in the plasma or the flame which is montiored by at least one radiation detector to measure the intensity of the radiation emitted by the plasma or flame in the wave length bands which are characteristic of the first and/or second material. ADVANTAGE - The method makes it possible to stop processing as soon as the required level has been reached. - The figure shows the system for etching plastic coatings off electrical terminals which have been sprayed with polymer as they are parts of electrical components. The component (B) thus has terminals (A) coated with e.g. polyphenylenesulphide which must be removed by the laser beam (Ls). Beam detectors (Sd1, Sd2) measure the intensity of radiation (S) from the plasma and their signals are amplified (V1, V2) before being transmitted to an instrument. The instrument (AS) determines directly or by difference whether the coating has been etched away to the desired extent and whether accordingly the process can be stopped by a signal (Si); max. intensity at detector (Sd1) shows that all the coating has gone.

Patent DE-3941328-A1 (DE)
Inventor: FRICKE HELLMUTH
IPC: H05B39/10
Filed: 1989-12-14
Abstract: AC switches (TRH, TRN) are connected in both the main and standby filament circuit of a signalling lamp (L). As long as the main filament (HF) is switched on and is intact, the main filament AC switch (TRH) is switched through via input diodes, connected in reverse-parallel, of an optocoupler (U1). When current is flowing through the input diodes, the photo-transistor of this optocoupler controls a switch (S1) which is used, in this switching state, to switch off the input diode of an electro-optical AC switch (U2). If the main filament (HF) burns out and the switch (S1) is driven into the other position, the electro-optically controlled AC switch (U2) is switched through and, for its part, switches the standby filament AC switch (TRN) through. The feedback report on the operating state of the signal lamp to the control mechanism takes place via the optocoupler (U3). The main/standby filament switch is constructed using only a few, proven electronic components. It is used especially in railway signalling lights. <IMAGE>

IPC: E01B5/08
Filed: 1990-09-24
Abstract: The rail described is intended for use in the construction of permanent way for rail vehicles. The rail has good vibration-absorption characteristics and gives significant reductions in noise levels by virtue of the following design features: When designed as a tramway-type rail (1), the width (B) of the groove (2) is greater than the groove width in a normal tramway-type rail and a shaped-section strip (3) of elastic material is fixed to the outer flank (2a) of the groove (2), the strip being of a thickness (D) such that the distance (A) between the shaped-section strip (3) and the inner flank (2i) of the groove (2) is equal to the groove width in a normal tramway-type rail; and/or a strip of highly wear-resistant material is attached to the side of the rail head along which the flange of a wheel of a rail vehicle travelling along the rail (1) runs and to the side of the groove (2) opposite the exposed surface of the shaped-section strip (2).

Title: Doffer to remove bobbins from stations - loads creel with bobbin holders closer together than bobbin winder interval to save creel space
Inventor: MUENNEKEHOFF GERD
IPC: B65H67/06
Filed: 1990-10-05
Abstract: The doffer, to remove bobbins from a number of stations, with a carrier to place the full bobbins in a creel, has a creel with a smaller bobbin holder interval than the winder spacing. The bobbin carrier system, on the doffer, has a movement component parallel to the line of the machine and advances in steps which are a whole multiple of the difference between the bobbin winder and creel spacings. The bobbin conveyor can also be moved vertically, and a number of bobbin holders in the creel are arranged in vertical rows with a fixed vertical interval between them, and a number of such rows are arranged next to each other along the line of the winding machine. The holders of neighbouring rows are displaced by one-half of the vertical interval. The holders are spindles extending to the front of the creel towards the machine. ADVANTAGE - The appts. gives a creel which can hold the required number of bobbins, but in a restricted space.

Title: Filling hollow car component with foam - using outer film bag containing two bags filled with foaming reagents, bursting them so that mix expands through e.g. slits to fill outer bag
Inventor: HUBER WALTER
IPC: B29C44/36
Filed: 1990-12-07
Abstract: Device for filling a space (particularly in a car component) with a two-reagent resin foam has two channels containing the respective reagents and an outer envelope of a plastic film which holds the two chambers loosely. The chambers have fracture points or thin walls so that they can burst by pressure from a finger or hand and their two reagents can be mixed together by working the outer envelope. The envelope is made of an elastic and soft material with a number of fine perforations made without loss of material; the volume of the envelope is less than that of the foam produced from the two reagents so that when they react together a part of the foam expands outwards through the perforations, fills the space, and bonds to the envelope itself. Preferred material for the envelope is polyurethane film. ADVANTAGE - The set-up used is simple, easy to handle and is filled so well that the infill bonds to the envelope wall.
